Abstract:
OkTEX is a TEX format based on plainTEX and on packages OFS, LANG and IENC. It is an experiment of making a new language enwironment for plainTEX users. May be, it is more powerful than well known Babel package. The new package LANG cooperates with OFS and supports language switching including declaration of arbitrary font encoding for each language. The next package IENC is under development. It gives possibility to set conversion from input encoding to font encoding and it cooperates with the LANG package and with encTEX extension (if such extension is available in the TEX distribution).
